1 The Dublin Core Collection Description Application Profile Pete Johnston UKOLN, University of Bath Chair, DC CD WG Collection Description Schema Forum, London 12 February 2004 http://www.ukoln.ac.uk/

2 http://www.ukoln.ac.uk/ Outline DC metadata & "application profiles" DC Collection Description AP –Background –Terms Used DC CD AP, RSLP-2000 & "RSLP- 2004"?

3 http://www.ukoln.ac.uk/ Dublin Core Metadata DCMI developing interoperable metadata standards to support resource discovery Defines, maintains, supports use of metadata vocabularies (DCMI Namespaces) –Sets of DCMI terms For each DCMI term –persistent, globally unique identifier –name –type of term (DCMI typology) element, element refinement, encoding scheme –definition, notes on usage –description of relation to other terms

4 http://www.ukoln.ac.uk/ Resources, statements, descriptions, records Terms used in statements about resources –anything that can be named or described Each statement has the form –Resource – Property -> Value (Resource) DCMI elements/element refinements are properties c.f. E-R model, a DC statement may describe –an attribute of an entity –a relationship between two entities A description is a set of statements about a single resource A record is a set of one or more descriptions of related resources

5 http://www.ukoln.ac.uk/ DC Application Profiles A DC Application Profile specifies –Which properties are used within a metadata application –May describe how properties constrained/adapted for purpose (semantic refinement, cardinality, value space) –Syntax-independent e.g. Simple Dublin Core –Use of properties from one vocabulary (DCMES) –To create (very simple) descriptions of… pretty much anything! e.g. RSLP-2000 –Use of properties from several vocabularies –To create descriptions of a Collection, its Location, Agents e.g. DC CD AP –Use of properties from several vocabularies –To create descriptions of a Collection

6 http://www.ukoln.ac.uk/ DC Collection Description WG Background –Growing interest in use of collection-level metadata to support resource disclosure/discovery –RSLP CD Model and/or RSLP CD-2000 schema implemented by several initiatives in UK –Significant influence on other CLD metadata schemas –Status, ownership, persistence issues Charter –Provide forum for sharing information about CLD activity –Develop a DC AP for collection-level description –Develop supporting materials for use of AP http://dublincore.org/groups/collections/

7 http://www.ukoln.ac.uk/ DC Collection Description AP For simple collection-level descriptions Suitable for a broad range of collections Primarily to support discovery and selection of collections A "core" set of collection description properties to support interoperability Informed by experience of RSLP, CD Focus (UKOLN), TEL, JISC IESR, IMLS, others Collection properties (only) of RSLP-2000 as starting point for WG discussion –exclude Location, Agent description (for now…)

12 http://www.ukoln.ac.uk/ Outstanding Issues for DC CD WG/DCMI Decide on how to describe format of items in collection Proposals for additions to DCMI Namepaces –provenance, isAvailableAt –isDescriptionOf?, logo? Ownership/URIs of collection-specific terms Review in light of DCMI work on dates, rights, modelling Encoding schemes? Develop supporting materials –guidelines, schemas, crosswalks Clarify administration of DC CD AP

13 RSLP-2000 RSLP-2004 DC CD AP, RSLP CD-2000 & "RSLP-2004"? DC CD AP DCMES

14 http://www.ukoln.ac.uk/ DC CD AP, RSLP CD-2000 & "RSLP-2004"? What are your requirements for CLD metadata schema(s)? Does DC CD AP meet your requirements? Does RSLP-2000 meet your requirements? Would a revised "RSLP-2004" meet your requirements? If more than one CLD metadata schema (e.g. DC CD AP & "RSLP-2004"), what are relationships? –technical issues, administrative issues … etc!
